word type: poker slang
- The first card revealed when a dealer spreads the flop in Hold 'Em or Omaha, or the first upcard dealt in stud.
Windows of Opportunity
In Stud, window cards are tracked carefully by players in the game, as it is very important to be aware of all upcards and dead cards in order to play correctly.
In poker games that use a board, it is simply the first of three cards exposed on the flop and is only significant as a curiosity or teaser.
